3 FunctionSystem informationThis device is a product of the KNX system and complies with the KNX directives. Detailedtechnical knowledge obtained in KNX training courses is a prerequisite to proper understanding. The function of this device depends upon the software. Detailed information on loadablesoftware and attainable functionality as well as the software itself can be obtained from themanufacturer´s product database. Planning, installation and commissioning of the device arecarried out with the aid of KNX-certified software. The latest versions of product database andthe technical descriptions are available on our website.

Intended use- Measurement and evaluation of the weather data: Wind speed, Precipitation, Twilight,

Temperature and brightness- Vertical installation on the outside of buildings, preferable in the roof and facade area

Weather station StandardKNX/EIB

Product characteristics- Integrated KNX bus coupling unit- Measurement data acquisition and limit value monitoring- Integrated heatingi The measured values apply to the mounting location. Variations to other weather services

– e.g. through local turbulence or areas with build-ups of air – are possible.

Figure 3: Avoid spray water

Figure 4: Maximum load on the angular arm

Select a mounting selection in which the weather station is not influenced by local obstacles orshading, such as surrounding trees, chimneys, awnings, etc. The sensor must be able to detectwind, rain and ambient brightness without impedance. Do not mount it below or next to building sections, from which water can drip onto the device.Select the mounting location so that the weather station will be accessible for maintenancepurposes.In the case of flat roofs, locate the weather station as close to the centre of the roof as possible. Minimum distance to surfaces below the weather station: 0.6 m (Figure 2). Otherwise, thesensors on the underside may get damaged by penetrating spray water (Figure 3). Direct sunlight, chimneys or other waste gas or ventilation systems affect the temperaturemeasurement.Do not operate in the vicinity of radio transmitter systems. Doing so will compromise function.Installation on tubular mast with separate mast fastening (see accessories).

Mounting and connecting the device

Figure 5: Terminal box opened

o Open terminal box.o Route the cables for the power supply and bus connection through one of the two cable

entries (11) and into the terminal box (3).o Fasten lower part of terminal box e.g. to a building wall, tubular mast.o Connect supply voltage to connecting terminal (9).o Connect KNX bus line to connecting terminal (10).o Connect connecting plug of the sensor head (1) to sensor terminal (8) in terminal box (3).i The angular arm (2) may break when the terminal box is closed. The angular arm must not

be used as a lever (Figure 4). o Set device on lower part of terminal box from above and snap in at bottom.

Aligning the device

Figure 6: Orienting the weather station

o Align the sensor head in the appropriate direction or - depending on the detailed on-sitecircumstances - according to the alignment of the facade (Figure 6).
